Amber Portwood's dishing on her upcoming wedding once again! Shortly after the Teen Mom star finally revealed her wedding date—get ready for an October ceremony!— she recently caught up with People to divulge some details on her wedding planning thus far, including the guest list! While balancing a growing online boutique—Be Forever Haute—and being mommy to little Leah, her fiancé, Matt Baier, has swooped in to help with all of the details regarding the big day. But the question fans are begging the reality star to answer is, who from the Teen Mom series will be invited to the ceremony?

“[Matt] is completely into it, even more than me maybe,” she said of the 45-year-old. “He is writing down the guest list and we already have 200 people on it, I don’t even know 50 of them! Every single Teen Mom [star] will be invited. Every single one from Teen Mom 2 and Teen Mom OG.”

Further, Portwood has been totally lax throughout the planning process. “I don’t know if I feel frantic or anything,” she continued. “I’m kind of scared. Not for any particular reason—just the fact that I’m getting married. We are on time and we pretty much know exactly what we want to do. We’re just trying to stay level-headed, because there’s a lot going on right now.”

The 26-year-old previously revealed she'd be designing her own dress, which would have "something with a late '40s to early '50s style." She expanded on the gown's overall look during her interview with People.

"It’s kind of see-through but not. [It has] certain jewels on it, [and is] body-forming and flared out at the end with a long train. I’ve went to a couple of stores and looked at dresses that are very similar and I got a lot of ideas.”
